A simple and dual‐target method based on ultra‐performance liquid chromatography/quadrupole time‐of‐flight mass spectrometry combined with dual‐bioactive [nuclear factor‐κB (NF‐κB) and β2‐adrenergic receptor] luciferase reporter assay systems was developed to rapidly characterize the chemical structure of various bioactive compounds of TCM preparations.

An HPLC‐MS/MS method has been developed and validated for the determination of venlafaxine enantiomers in human plasma and applied to a pharmacokinetic study in healthy Chinese volunteers. The method was carried out on a vancomycin chiral column (5 µm, 250 × 4.6 mm) maintained at 25°C. The mobile phase was methanol–water containing 30 mmol/L ammonium acetate, pH 3.3 adjusted with aqueous ammonia (8:92,...
